Application led November 2.9, 1918. Serial No. 264,659.

. To all whom t may concern:

Beit known that I, SIEGMUND BACHMANN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Boxes, of which the following is a specification.

My invention relates to improvements in boxes more commonly formed of flexible box-board and involving a base, surrounding walls extending upwardly from the base, corner extensions connected with the walls of the box, and means engaging the said extensions when the box is in erected condition, for holding the box against collapsing. Y

My primary object is to reduce the cost of construction of boxes of the type referred to, without impairing their resistance to collapsing, when in erected condition, my invention involving to this end, the use of the minimum amountV of box-board.

Referring to the accompanying drawings Figure 1 is a perspective view, with certain parts broken away, of a box of the hat-box type constructed in accordance with my invention. Fig. 2 is a plan view showing a` corner portion ofthe box Iblank from which the box of Fig. 1 is constructed. Fig. 3 is a broken section, taken at the line 8 on Fig. 1, and viewed in the direction of the arrow. Figs. 4 and 5 are sections taken at the lines 4--4, and 5-5, on Fig. 3 and viewed in the direction of the respective arrows. Fig. 6 is a plan view of a corner portion of a blank for forming a box constituting another embodiment of my invention. Fig. 7 is a vbroken sectional view of the box formed from the blank of Fig. 6, this section corresponding with Fig. 3; and FiO. 8, a section taken at the line 8 8 on Fig. 7 and viewed in the direction of the arrow. Fig. 9 is a plan view of a corner portion of another blank for forming abox constituting another embodiment of my invention. Fig. 10 is a broken section of the box formed from the blank of Fig. 9, this section corresponding with Fig. 3; and Fig. 11, a section taken at the line 11-11` on Fig. 10, and viewed in the direction of the arrow. Fig. 12 is a plan view of a corner portion of another blank for forming a box constituting another embodiment o f my invention. Fig. 13 is a broken section of the box formed from the blank of Fig. 12, this section-cor- 'bodiment of ,my invention.

Fig. 24 'is a plan view of a' corner portion of another blank for'forming av box constituting another em- Fig. 25 is a view likeFig. 19, with a wall and the corner extension shown folded over upon adj acent portions of the blank. Fig. 26 is a section like Fig. 3, of this portion of the box, showing it in erected condition; and' Fig# 27 is a section taken at the line 2701i Fig. 26 and viewed in the direction of thearrow. Referring to Figs. 1, 2, 3, 4, and 5, one of the four similar corner portions of the blankA creases to facilitate folding the parts. The' lines 24 and 25 intersect each other to form the lfour corner vportions or corner extensions 28", oneV only of which is shown in Fig-2, which arehingedly connected with of the blank and with the locking flap the ends of the walls l27 and 28 along the 'f thereto yalong a folding outerl extremities of the lines 24 and 25 as shown, each of the corner extensions "being provided with a diagonali Afolding#"lline' 29 which extends from the point of intersection of the folding lines 24 with the folding lines f25 toward the outer extremities of the cor-' ner extensions.

In vthey particular construe# tion shown, the edgey portion 30rof' each. corner extension 28 is cut-away as indicated at 3l, the outer` ends of the diagonallines 29 coinciding with these cut-.away `portions. Also, the outer edges of .the walls l27 and -28 v.are .provided with flaps 32 rand 33 .re

` spectively connected therewithalong .fold- 37 of each corner extension :is provided at yan edge thereof with a flap .38 connected Y line 39 which :is substantially .in line with the folding line 35, the lflaps 38. and 33 .being separated by the .space'40 .and .the corner section .37 be- 'ingsevered along linesl .41 and 42 to Yform a lap 43 for apurpose'hereinafter described.

The box ymay vbe formed from the blank asl stated, as follows.: .By turning Vthe opposite `walls27 upwardly and inwardly, and with themthe corner extensions, to .cause the walls 2.7 to overliethe'base26 :and the .corner extensions tooverlie the walls .28. The inner .ends of the laps 43 may `.then be secured .to the wallsf28 insany suitable .manner as 'by ymeans of the ystaples indicated .at 44, which fleaves .the outer extremities `of the laps 43 free to-.be..fiexed,the inner portions of the sections 37y "bein-g secured .in fixed relation to the walls A28 1n Vany suitable'manner, as for example by stapling means, these means .in the illustrated construction Vbeing asin- -gle staple represented at 45 avhich passes through the lsections 37 .of both `corner extensions at one end of .the box, .due to the fact that in the particular constructions V.sl'1own,1the Yproportions of 'the'box .are such that the sections V37 overlap eachother. To erect .the box, the operator swings .the walls .2.7 npwardly and outwardlyfand the walls 28 l upwardly and inwardly `along their hinged connections .fwith thebase 26 to va .position lin which these walls extend'at lright-angles .tothe base :26. In thus manipu- -lating the structure, the sections-36 swing at their fhinged connections with-:the sections and vwalls .-27 along .the foldingI lines 29and 24, respectively, to aifposition where they llie fflatwisev yagainst the adjacent sec- .tions' 37 fof. the corner extensions, as illus- Y trated-in the drawing, the .operaterf'in this v operatienfspringing .the .outer vends of-` the -laps-f43 in, an .upward directitm. to [permit "the sections 36 for holding the latter in corresponding with the locking 'flaps 43 rof of the upper edges of the sections 36swingingback of these laps, whereupon, on releasing the-grasp on'these laps, they will spring into overlapping position relative to place and therefore the walls of the Vbox in erected condition. .The iaps 38 in.- this operation are folded: to lie between the sections 37 and the walls 28 as shown in Fig. 5, thus forming a reinforcement for the up- Iper edge of the box,v and the flaps 32 Vand 33 are bent to extend inwardly, preferably ata right-angle to thewalls fof the box, to

form `a reinforcing flange extending l'continuously around the top `of jthe box,vcertain of these flaps in Fig. l being shown broken Y away todisclose details .which would otherwise` be hidden. n

The construction Aillustrated in Figs., 6,- 7, and 8, is the same `as that shown in the preceding figures, except that .the flaps 32, 33, and 38 areomitted and .instead of cutting the llap 43, as shown in Fig. 2, this lap,

Yrepresented in? Figs, 7, and 8, at46,v is.

cut from the corner section 37 along the line 47 curved at-its ends as indicated at 48. The blank maybe folded as .described of that 'of the preceding figures, .but instead -of providing a single staple 44-.forv eachlap 46,` each lap 46-is preferablystapled along its upper edge to the underlying wall 28 by the plurality fof staples represented at 49. Y. The lower edges of the laps 46 are therefore adapted to be swung out of thepath ofy movement of the corner Vsections 36. in the erectingfof the box and when released, after erection, overlap the sections 36 and hold the box in erected condition. In the convstruction illustrated in Figs. 9,V 10, and [11, the walls 28 vand corner-sections 37 are provided with flaps-represented at 50 and 51 connected with these walls and sections along folding lines 52 and 53, theV sections 37 .being vprovided with locking flaps 54 ioo Fig. 2 which `are cut from the section 37 n along the lines 55, 56, and .57, the line of severance ruiming from one 'point on thefolding line 53 to-another point thereon, as shown..

Theblank is folded as described ofthe blank Y of Fig. 2, the flaps 5l overlying the flaps 50, andthe fastening device, as forexample,

astaple 54a securing each lap 54, `at itsV in- .the sections36 of the' corner extensions for v holding'tlie"box .wallsi-n erected condition.

rllheflaps50V and 51 may be turnedMin-wardly to-i--einforce the upper edges fof thebox as -explained.ofthe naps-'.32 and 33 in Fig. l.`

:The-construction .illustrated in Figs. `l2, ,13,and 14, is substantially .the same as ithat illustrated in Figs. ,1: to 5, inclusive, except. f 1 that the Yflapsjf32tand' 38. .are omitted.` In 1304 y this construction wherein the parts are 'Y given the same designation throughout as in l figures, are folded upwardly and inwardly function.

and then downwardly to overlie the laps 43 as represented, the staples 44 passing also through the iaps 33, and while the laps 43 are entirely severed at their outer ends, from the corner sect1ons'37, the overlapping portions of the flaps 33 operate to hold these laps against displacement. v

It -will be noted that all of the construe tions described are of the so-called' automatic box type or, in other words, areof that type of box which may be erected from collapsed condition without requiring the application of fastener devices to the box vafter erecting it, or the tucking of tongues or the like into slits to effect the locking However, my invention is also applicable to boxes of what might be termed the non-automatic type, the embodiment of my invention in three different forms of boxes of thisl last-referredto type being illustrated in Figs. 15 to 23, inclusive.

Referring particularly to the construction illustrated in Figs. 15,16, and 17 one ofthe similar corner portions of the blank from which this form of box is made is illustrated in Fig. 15, this blank having parallel folding lines 57 and 58, corresponding with the folding lines 24 and 25 of Fig. 1 and forming a rectangular base portion 59 with surrounding wall-portions 60 and 61 corresponding with the wall-portions 27 and 28 of Fig. 1. The lines 57 and 58 at the four corners of the box blank intersect and beyond their points of intersection form the corner extensions 62. eachof which has a diagonal folding line 63, and a flap portion 64 hinged at 65 and extending in line with a flap portion 66 hinged at 67 to the outer edge of the adjacent wall-portion 61 at opposite edges of the blank, the fiaps 64 and 66 being preferably connected together along a folding line 68, kas shown of one part in Fig. 15. Thediagonal folding line 68 of each corner extension 62 divides the latter into two triangular corner sections 69 and 70, the sections 70 having cut therefrom along the lines 71, 72,`and 73, a tongue 74 which extends up to the folding line 65, and the corner section 69'eontains a slit represented at 75 and extending preferably at a right-angle to the folding line 65 when the blank is in the flat condition shown in Fig. 15. In forming a box from the blankl of Fig. 15, the side walls 60 and corner extensions 62 may be folded upwardly and downwardly to oppose the base 59 and walls 61 in which condition the flaps 64 are secured to the underlying flaps 66 by any suitable meansxas,'for example, staples, as indicated at 76. .To erect the box, .the walls 61 are swung `upwardly and toward each other on the base 59 and the walls 6() are swung upwardly and away from each other on the base, the corner sections 69 swinging along the diagonal lines y63 and the lines 57 to a kposition in which they extend vat right-angles to the walls 60 and iatfwise' oppose the adj acent corner vsections 70, the operator in vthis movement of the parts lifting the tongues 74 to clear those edges of the corner sections 69 which ext-end uppermost when the box is erected, as indicated at 77. The tongues 474, one for each corner oflthe box, thus extend inwardlybeyond the corner sections 69 and may be inserted through the slits 75 to extend at their lower portions between the sections 69 and70, and overlap both of 'thesesections at their upper portions, 'thus securely holding the box in erected condition. The Hap portions 64 and 66 lmay be'turned inwardly to they angular position shown particularly in Fig. 17,

`wherein they form a reinforcement for the upper edge of the box. Y

'The construction shown in Figs. 18, 19, and 20, is the same as thatfillustrated in Figs. 15, 16, and 17, except that the flaps 64 and 66 are omitted and the locking tongues,

`represented at 7 8 and correspondingwith the locking tongues 74 of the preceding figures,

y extend short ofthe edges of the corner sections 70, considering the position shown in Fig. 18, and the edges of the corner sections 69 which are uppermost when the box is `erected are cutaway as indicated of the one section at 7 9 in they drawing. In this construction of box, the corner sections 70 are secured to theunderlying walls 61 as by means of staples preferably at the points indicated in Fig. 19. In the erecting of this construction, the parts are manipulated and interlocked as explained of the construction shown in Figs. 15, 16, and 17.

The construction illustrated in Figs. 21, 22, and 23, is like that of Fig. 15, except that thel tongue represented at 81 is of the hook variety, the rtongue-.receiving slotv representedqat 82 and corresponding with the slot 7 5 of Fig.l 15, extends at a different angle,

the outer edges of the sections 69 are cut y65 to extend between the corner seotions70 and the walls 61, it being preferred that the flaps .64-bef;glued f to the walls 'G1-iii; the posif rtion stated, .and :that the zflaps :66 i be .turned oven-to overlie the `upper edges ofthe tongues 81: to which .,-l'atter-Y the flaps .'66 `arepreferably tglued. :Int erectingrthe box, .the .walls GOend 61 lare swung on thebase 59:.as described of the construction illustrated -in vFig. 15, @the operator in `this :operation swinging :the
